Polykleitos

Polykleitos was a 5th and 4th century BC Greek sculptor in bronze. His statues were some of the first contrapposto statues, depicting the human being in a state of having the shoulders and arms twist off-axis from the hips and legs, giving the statue the illusion of being in motion. Polykleitos also invented the "Canon", a set of proportions of the measurements of the human body which would be applied to the making of human sculptures.
